Description
Technical field
The present invention relates to wiper or similar device, more particularly to a kind of rainwater self-circulation type rain shaving electrical machine cooling device.
Background technology
As the windscreen wiping system for automobile for ensureing driver and getting a clear view, its safe and reliable operation, travel safety is directly determined.
Under rainwater operating mode, windscreen wiper system long-time full-load run, motor seriously generates heat, if now easily causing without good heat radiating measure
Motor ablation, insulation breakdown, cause motor damage, influence travel safety.
Traditional rain shaving electrical machine is motor body and slowing-down structure assembly, and surface is natural cooling shape directly and air contact
Formula.Superficial air flowing is current stabilization, category air, metal fever exchanging form, air surface heat transfer coefficient 0.0242（W/（m·
℃））, radiating effect is poor.When motor operation heating is serious, it can not in time radiate, system safety can not be ensured.
The content of the invention
To solve the above problems, the present invention proposes a kind of rainwater self-circulation type rain shaving electrical machine cooling device, its is simple in construction,
It is reasonable in design, be easily installed.
The technical solution adopted in the present invention is：A kind of rainwater self-circulation type rain shaving electrical machine cooling device, including drainage
Part, it is characterized in that：Also include the motor water cover with water inlet and delivery port, the inner surface setting of motor water cover has for rain
Water flows through the water channel on rain shaving electrical machine surface.
The a kind of of rainwater self-circulation type rain shaving electrical machine cooling device as the present invention is improved, and described motor water cover is set
In the outer surface of rain shaving electrical machine, the external diameter of motor water cover is slightly less than the external diameter of rain shaving electrical machine, the two interference fit.
The another of rainwater self-circulation type rain shaving electrical machine cooling device as the present invention improves, and is less than in motor draw ratio
In the case of certain threshold value, spiral channel is used in motor water cover；In the case that motor draw ratio is more than above-mentioned threshold value, motor
Axial water channel is used in water cover.
As the further improvement of the motor water cover inner lead of the present invention, described water channel is spiral channel, along motor water
Cover inside diameter hoop direction, arrival end to the port of export from motor water cover are provided with the spiral shape water that motor surface is flowed through for rainwater
Groove, tank are connected with water inlet, the delivery port of motor water cover.
Another kind as the motor water cover inner lead of the present invention further improves, and described water channel is axial water channel, edge
Motor water cover is axially disposed within motor water cover inner surface, is end to end a few font tanks, and the tank enters with motor water cover
The mouth of a river, delivery port are connected.
As another improvement of the rainwater self-circulation type rain shaving electrical machine cooling device of the present invention, the section of described water channel
To be square or circular.
As the present invention rainwater self-circulation type rain shaving electrical machine cooling device another improvement, described drainage part be with
The aqueduct of windscreen grid connection, the aqueduct are plugged in the water inlet of motor water cover.
Advantages of the present invention and beneficial effect are：The rainwater self-circulation type rain shaving electrical machine cooling device, including with entering water
The motor water cover of mouth and delivery port, the inner surface setting of motor water cover have the water channel that motor surface is flowed through for rainwater, the water channel knot
The water route of structure is smooth, and resistance to water-flow loss is small；Be not in because there is temperature gradient in motor intake-outlet both sides and caused by three-phase
The inconsistent phenomenon of winding temperature, radiates than more uniform, will not produce thermograde at motor both ends, its is simple in construction, manufacture
Simple process, it is easily worked.Additionally by set the section of water channel to be square it is circular or in addition to above-mentioned shape other are suitable
Shape is closed, increases guide groove sectional area as far as possible, makes radiating effect obtain arriving very much raising again.

Embodiment
Below in conjunction with the accompanying drawings 1~4 and embodiment the present invention is elaborated, describe below only as demonstration
And explanation, any formal limitation is not made to the present invention.
Embodiment 1:
The rainwater self-circulation type rain shaving electrical machine cooling device that the present embodiment uses, including drainage part and with the He of water inlet 3
The motor water cover 4 of delivery port 6, the inner surface setting of motor water cover 4 have the water channel 5 that the surface of rain shaving electrical machine 1 is flowed through for rainwater.Water channel
5 section for it is square or circular or can increasing heat radiation area other shapes.
Drainage part is the aqueduct 2 connected with windscreen grid, and the aqueduct 2 is plugged in the water inlet of motor water cover 4.
Motor water cover 4 is arranged on the outer surface of rain shaving electrical machine 1, and the external diameter of motor water cover 4 is slightly less than the outer of rain shaving electrical machine 1
Footpath, the two interference fit.
Embodiment 2:
The present embodiment and the difference of embodiment 1 are：Water channel is selected according to motor draw ratio.The present embodiment sets threshold value
For 2, in the case where motor draw ratio is less than 2, use spiral channel 7 in motor water cover；When motor draw ratio is more than 2 situations
Under, axial water channel 8 is used in motor water cover.
Water channel 5 is spiral channel 7, along the inside diameter hoop direction of motor water cover 4, from the arrival end of motor water cover 4 to the port of export
The spiral shape tank that the surface of rain shaving electrical machine 1 is flowed through for rainwater is provided with, tank is connected with water inlet, the delivery port of motor water cover 4
It is logical.This form water route is smooth, and resistance to water-flow loss is small, be not in because there is temperature gradient in motor intake-outlet both sides and caused by
The inconsistent phenomenon of measuring temperature of three-phase winding.
